[Plugin: GD Star Rating] Prevent Comment Submittion Without Voting (Comment Integration)

Hi, first of all, thanks for this fabulous job.

I’d like to know if there’s any way to prevent users who haven’t yet voted on mi multi-rating block to submit their comments.

I’m using comment integration for articles and couldn’t manage to find a solution to this.

I’ve made the integration through this code using some actions:

if (defined("STARRATING_INSTALLED")) :
	add_action( 'comment_form_after_fields', 'add_rating_block');
endif;

function add_rating_block() {
	wp_gdsr_comment_integrate_multi_rating(1);
}

I’ve been looking a lot in the forums and couldn’t find the answer to that. I’d like to show a message like “You need to vote first if you want your comment to be submitted” or something like that.

Any help would be really appreciated.

Thanks,
Jose
